Function keys on Das Keyboard?

I was wondering if there is any way to map the functions keys onto a Das Keyboard? I would primarily like to map the volume, play/pause, and mute function keys. Is there a program that would allow me to do this?

Thanks for the reply! It seems to work perfectly, although pausing/playing a song seems to move the song back a second, which is strange, but definitely something I can live with. Thank you for showing me BetterTouchTool!
